MIXING APPARATUS.

Specification of Letters Patent.

Patented Feb. 1'7, 1914.

Application filed April 14, 1913. Serial No, 761,046.

To all whom it may concern Be it known that I, Lrvines'ron A. THOMP-SON, a citizen of the United States, and resident of Milwaukee, in thecounty of Mil-.

waukee and State of Wisconsin, have invented certain new and usefulImprovements in Mixing Apparatus; and I do here.- by-declare that thefollowing is a full, clear,

' and exact description thereof.

The primary object of my invention is to provide a simple, economicaland effective mixing apparatus, the same being particu-' ranged a rimfor nested engagement with the container bottom, whereby these twoseparable members in conjunction form' a fluid chamber, and to provide afluid nozzle in conjunction with the base, wherebyfluid under pressureis directed against the propeller, and. also to provide the base with asuitable exhaust aperture or discharge.

I am aware that devicesiof this type have been utilized wherein electricenergy is employed for imparting motion to the gener-.,

ator, the energy being controlled by a suitable connection efi'ectedthrough enga-ge-- ment of a base and a liquid container. The utility ofthis type of device, however, is limited, duetothe fact that in-amajority of instances, the necessary electrical current for operatingsaid device is not accessible. Hence my apparatus is arranged to meetthe more general requirements, it being under stood that said device isto be operated more particularly by water under pressure, which isgenerally accessible in most localities, 'although it is understood thatI may, without departing from the spirit of my invention, utilize otherfluids for accomplishing the desired result.

With the above objects in view the invention consists in certainpeculiarities of construction. and combination of mechanical elements ashereinafter fully set forth with reference to the accompanying drawingsand subsequently claimed.

In the drawings Figure 1 represents a partly sectional elevation of amixing apparatus embodying the features of my invention, the sectionbeing indicated by line 11 of Fig. 2, and Fig. 2, a plan view of thebase member of the mixing apparatus, the. same being shown partly insection as indicated by line 22 of Fig. 1.

Referringby characters to the drawings, 1 represents a portable vesselor container hav- .ing a valanced or flanged bottom. 1, the

lower edge 2 of the flange being suitably turned to form a finishedtight joint in connection with a rim 3 of a base-member 4, whichbase-member is hollowed as shown,

within the confines of the rim, to provide a fluid-receiving cavity 5that is formed' in conjunction with the inverted cupped bottom of thecontainer. The fluid-receiving cavity has extending from its walls atangentially disposed exhaust nozzle 6 that may be connected by aflexible pipe 6 -to a waist, which exhaust connections form no part ofmy invention. Extending across the fluid chamber 5 is a hollow web -7having oppositely disposed discharge nozzles 8, 8, through which nozzlesfluid is,directed to the blades of a propeller 9 that is disposedthereabove, the same being hereinafter more particularly described.Fluid is supplied to the Web 7 and its nozzles by means of a suitablevalve-controlled pipe connection 7 that is tapped to any convenientsource of supply. The rim 4 of the base, as shown. is preferablyprovided with a suitable gasket 4, which gasket serves to form a moreperfect seat for the container valance orflanged edge.

Journaled in the bottom 1 of the container is a spindle 10, to the lowerend of which spindle the propeller is secured. The upper end of thespindle extends into the bottom of the'f yessel and carries 'an,agitator 11, whereby the contents of thei essel are thoroughly mixed,the said agitator being cent-rally disposed therein. From the foregoingdescription it is apparent that the portable container'or-vessel 1, whenfilled with the ingredients". to be mixed, is thereafter seated upon therim 4 ,posed above the plane of Thereafter 9 by manipulation of thevalve carried by the feed or supply pipe 7 whereby the fluid isdischarged in opposite directions through the nozzles 8 and 8, the jetsbeing directed against the vanes or blades of the propeller, to thuscause rapid rotation thereof, the spindle and the agitator being-therebyrevolved to effect the desired mixing operation. The thin jets of fluiddischarged from the nipples are exhausted from the fluid chamber throughthe exhaust nozzle 6 and when the mixing operation has been completedthe valve in pipe 7 is turned, to cut off the supply. Thereafter thevessel or container can be removed and emptied of its contents,particular attention being called to the fact that the propeller isdisthe lower edge *2 of the container valance or flange, whereby thesaid container can be supported upon its bottom without liability ofthepropeller coming in contact with the counter or table, upon which theaforesaid container rests when not seated upon the base.

I claim;

1. A mixer comprising a separable containei' having an integral. bottomand a base member, the container bottom being arranged to fit upon thebase to form a closed fluid chamber in conjunction therewith, means inconnection with the base for admitting fluid to the chamber underpressure and for exhausting said fluid therefrom, an agitator revolublymounted within the container. a propeller revolubly mounted within thechamber, and connecting means for the agitator and propeller extendingthrough the container bottom.

2. A mixing apparatus comprising a portable container having a flangedbottom, a

' spindle extending through the bottom, an

agitator carried by the spindle, the same being within the container, apropeller sepower is applied to the propeller cured to the spindle belowthe container bottom, a hollow base member having a rim adapted. toreceive the whereby a closed chamber is formed between the base and saidflange, and means in connection with the base for admitting fluid underpressure to the chamber and exhausting said fluid therefrom.

3. A mixing apparatus comprising a container having a rotatory agitatortherein, a stem carried by thev agitator and extending through thebottom of said container, a propeller secured to the stem, a seatingflange extending from the container bottom about the propeller and belowthe plane of the same, a hollow base having a rim adapted to receive thecontainer flange whereby a tight joint is formed between the base andsaid container, and means for admitting irnd exhausting fluid to andfrom the hollow Jase.

4. A mixing apparatus comprising a con tainer having an inverted cuppedbottom, a spindle journaled. in the bottom, an agitator disposed withinthe container and car ried'by the spindle, a propeller arranged withinthe cupped bottom portion of said rontainer and secured to the spindle,a hollow base having a rim for seating engagement with the edge of thecupped bottom of said container, a discharge nozzle carried by thecontainer for directing fluid under pressure to the inclosed propeller,and means for exhausting said fluid from the base.

In testimony that I claim the foregoing I have hereunto set my hand atMilwaukee in the county of Milwaukee and State of Wisconsin in thepresence of two Witnesses.
